Definitions
- Automatic bowling scorer systems that include score printing apparatus are known in the art.
- the printers print the game score data at the completion of each frame of the game.
- the paper onto which the frame-by-frame and game total scores are printed already has printed thereon a bowling scoresheet grid pattern which defines the areas where the players' frame-by-frame and game total scores are to be located.
- the frame and total scores are not always printed in the designated areas defined by the grid pattern. This problem is compounded by the fact that players do not always bowl in their assigned sequence, in which case the next score to be printed may be above or below and/or to the left or right of the last printed score. Therefore, typically, the printer portion of an automatic bowling scorer system is one of the more complicated and least reliable portions of that system.
- a printer having a linear array of dot print elements. Five successive energizations of the array of dot print elements are required to form each character on an advancing strip of blank paper. Predetermined ones of the dot elements are activated on each energization of the array to form respective characters. After each frame score has been printed, all dot print elements are activated to print the vertical lines of the bowling scoresheet grid pattern.
- Designated ones of the dot print elements are activated with each energization of the array to concurrently print the horizontal lines of the grid pattern.
- the dot print array is of sufficient height to print the game score data for all the players on the team substantially simultaneously, frame by frame, based on the game score data stored in the random-access memory of the bowling computer.
- FIG. 1 is a block diagram of the printer and print control system.
- FIG. 2A is an exemplary score sheet printed by the printer of this invention.
- FIG. 2B is an exemplary frame score as printed by this invention.
- FIG. 3A is a detailed schematic of the means for transmitting control signals to the print head;
- FIG. 3B is a detailed schematic of the print head.
- FIG. 1 A block diagram of the overall system is shown in FIG. 1, and an example of the resultant printed scoresheet is illustrated in FIG. 2A.
- the printer 2 includes a printhead 4 and a stepping motor 6 for advancing a strip of thermally active paper past the printhead.
- the printhead 4 is comprised of two substantially identical printheads 4A and 4B mounted end to end. These individual printheads are of a design manufactured by Gulton Industries, Metuchen, N.J., the matrix used to selectively energize the dot print elements shall be fully disclosed herein.
- Each individual printhead assembly 4A, 4B has an arrangement of 67 dot print elements in a linear array so that the complete printhead assembly 4 has a linear dot array of 134 dot print elements.
- the dot print elements on the printhead 4 are individual thick firm resistor elements which heat up upon the passing of electrical current therethrough.
- the dot print element have a fast thermal cycle which permits them to heat and cool rapidly upon the application and termination of current flow therethrough.
- the surface of thermal printhead 4 is in contact with a strip of thermographic (heat active) paper and the heated print dot elements on the printhead 4 produce corresponding dots on the thermographic paper.
- the total vertical space to be imprinted is divided into 16 rows DR0-DR15.
- the upper printhead assembly 4A prints the top two horizontal lines L1, L2 associated with the heading to be printed upon the scoresheet (see FIG. 2A), the three horizontal lines L3, L4, L5 defining the scoresheet grid for the first three players and all rows DR1-DR7 of character data lying between these lines; the lower head 4B prints the lines L6, L7 defining the grid for the three lower players, the lines L8, L9 associated with player total information and all rows DR8-DR14 of character data lying between lines DR8-DR14.
- all dot elements are energized to print the vertical lines L10-L23 of the background grid.
- the thermal print heads are multiplexed, to minimize the number of signal lines that must be routed to them.
- the 16 rows DR10-DR15 are grouped into 4 quadrants, Q0, Q1, Q2, Q3 (see the right hand side of FIG. 2A). With 4 quadrants multiplexed it is no problem to maintain less than 25% duty cycle on each resistor dot element prolonging element life. This is true so long as all 4 quadrants are used for printing on each cycle, which is true in this system.
- the data print rows as numbered from DR1 through DR14 are divided for printing purposes into the following head/quadrant combinations:
- FIG. 2A has only 14 printed rows of data DR1-DR14, 16 rows are provided for in the above table. Rows DR0 and DR15 (marked with asterisks) never have character data to be printed, but control signals are issued as if the two lines do exist; blank characters (no dots on) are issued to rows DR0 and DR15. This scheme is used merely to simplify the overall design by avoiding the special cases at each end of the dot element array.
- the data to be printed is stored in the memory of the bowling score computer shown in the block diagram of FIG. 1.
- the computer includes a random-access memory 10 for storage of ball-by-ball, game and frame score data.
- Microprocessor MPU 12 performs data computation operations in accordance with a program stored in read-only memory ROM 14.
- Peripheral interface adapter PIA 16 is the communications link between the microprocessor 12 and its associated devices, i.e., random-access memory 10; read-only memory 14 and printer system 2.
- the PIA 16 recognizes an address and gives the microprocessor 12 access to that address.
- the microprocessor 12 is a Motorola 6800, and PIA 16, which must of course, be compatible therewith, is a Motorola 6820.
- the significant data outputs from the PIA 16 to the printer of this invention are the lines PB0-4 carrying the data which define each character to be printed in the rows DR0-DR14; printer storage register control signals E1-E3 for causing storage of the character defining data; phase drive signals S1 ⁇ S4 for energizing the dot print elements selected by the developed data to print each character, or to print the lines of the background grid; the signal V.LINE for causing a vertical line print; the signal H.LINE for causing horizontal line print; and the signal PAPER ADVANCE for energizing the paper advance mechanism 6. Provision is also made for transmitting a PRINT FAIL from the print head 4 back to the PIA 16; in the event of a failure in the printer head 4, data transmission is thereby halted.
- each character in each row DR1-DR14 of the full printout shown in FIG. 2A is printed by defining it in terms of the significant dots in a 5-by-5-dot matrix. It has been explained above that 4 quadrants, each quadrant comprising 4 rows, must be printed to print the full height of the scoresheet; and as shown in FIG. 2B, 5 print cycles in the row direction are required to print a complete character.
- the control signals to be discussed below provide for this character printing sequence.
- System timing requires only a simply counting routine for counting the width of a frame space, and the width of characters within the space, in accordance with the dot count sequence illustrated in FIGS. 2B.
- characters 9, 6, 6, 7, 7, would be stored in storage areas in RAM 10 allocated to print rows 4, 6, 8, 10, 12, respectively; no character would be stored for the other rows.
- the table lookup is performed for the stored characters, and a one of the five columns of dot character information is transmitted to the printer.
- This fetch routine is simplified by storing the characters to be printed in columnar array relative to one another in memory.
- the characters of the character column are converted through a lookup table into a binary word whose bits correspond to the darkened dots on the next dot column.
- each character being represented by a 5-by-5 matrix, 5 columns of dot format data are required to print all the characters in a given column.
- 5 lookups are performed of each character in the column to establish the 5 separate successive sets of dot column data representing vertical character segments that are necessary to print each character.
- a simple counting bit routine keeps track of which dot column within a given character column is being printed.
- the dot sets representing the character segments are transferred via the PIA to the register RG1-RG3 (FIG. 3A) via 5 data lines PB0-PB4 which are connected to each of registers RG1-RG3. Signals appear in succession on control lines E1-E3 to store the dot-representing data signals in registers RG1-RG3. In this manner the data signals for the first three rows of each quadrant (there being four quadrants to each column) are stored. The signals for the character segment defined for the fourth row of the quadrant are not stored in registers; they are applied directly to one side of the print head drive matrix as illustrated in FIG. 3A.
- the three registers RG1-RG3 each have 5 outputs for a total of 15 outputs connected respectively to print control leads M1-M15.
- the data lines PB0-PB4 are also directly connected to control leads M16-M20, a fourth subgroup of the dot print leads. In this way a quadrant including dot segments for 4 rows is prepared for printing, the registers RG1-RG3 and data lines PB0-PB4 providing the resistor selection signals to one side of the print matrix (FIG. 3B) on inputs M1-M20. It can be seen from FIG. 3B, the detailed schematic diagram of one of the two print head portions 4A, 4B that each print control lead M1-M20 runs to four dot print elements.
- control lead M6 runs to dot elements R10, R27, R44, R61. Which of these four dot elements is to be energized while a given data bit is present is determined by phase drive lines S1-S4. These signals S1-S4 are applied in succession; they are generated in sequence to follow the respective sets of data signals defining quadrants 0, 1, 2, 3 so that the appropriate data which has been stored in registers RG1-RG3 is applied to leads M1-M20 when the respective drive signal appears.
- the duration of application of drive signals S1-S4 is fixed by common multi-vibrator 30 (FIG. 1) enabled by a signal coincident with the leading edge of each of signals S1-S4; the one-shot multi-vibrator 30 is used so that timing is provided through the drivers 50,51,52,53 rather than by separate signals from the MPU.
- the dot resistors are selected by the data stored in registers RG1-RG3 by signals E1-E3, and by signals on the lines PB0-PB4 applied directly to the print head. Then signals appear on lines S1-S4, their duration limited to about 5 milliseconds by milti-vibrator 30 during which the dot pattern (see FIG. 3B) is thermally printed on the printer paper.
- Diode circuitry D1,D2, D3, D4, shown on the right hand side of FIG. 3A provides means for detecting the absence of a voltage drop across the phase driver transistors whenever these drivers are driven into cut-off.
- a printer-fail signal is generated for transmission back to the PIA 16 if these drivers are found to be shorted out; this signal is used to shut off the printer in order to protect the print heads.
- FIG. 3B it illustrates the relationship between the 16 rows DR0-DR15 into which data is divided for purposes of transfer to the print head, and the actual printing resistors of the thermal dot print elements.
- the figure shows the print head section 4A; print head section 4B is of like construction, with the only difference being clearly marked on FIG. 3B.
- Print head 4A includes 67 thick film resistors R1-R68 on a common substrate. The resistors to be energized to print each column of dots are selected by the data lines M1-M20; the timing of the print cycle is provided by strobe lines S1-S4.
- a resistor is energized to print a dot only when a signal is received both on a data line (M1-M20) and a strobe line (S1-S4). It is apparent, e.g., that lines M1-M10 control the printing of rows DR1-DR7, with the specific quadrant in which printing is to occur being selected by successive phase drive signals S1-S4. The selection and energization processes were explained fully above with respect to FIG. 3A, on which these lines also appear.
- FIG. 2B shows that each frame has the following vertical array:
- the frame of FIG. 2B could be printed in rows DR2 and DR3 of a frame score printout (FIG. 2A) using the following resistors:
- the wiring connections of significance in printing the game score background grid for these exemplary rows DR2, DR3, are the connection of resistors R34 between strobe line S2 and H-LINE signal input and the connection of resistors R17 and R7 between strobe line S1 and the H-LINE signal input to energize these resistors with every frame count signal (explained below) to print appropriate portions of horizontal lines of the background grid; and the connection (again taking only print rows DR2 and DR3 for an example) of resistors R18, R19, R25, R26, R32, R33 between the V-LINE signal input and common strobe S2 so that a continuous vertical line of the background grid including those dots never used to print character data can be printed.
- all the data lines M1-M20 and each of the strobe lines S1-S4 are energized to print the complete vertical line.
- the basic frame clock signal rate which is used to count the width of the frame is applied to the H-LINE wire to serve as that signal.
- a simple counter to count to 24 (the width of each of the frames 1-9) or 31 (for frame 10 and the TOTAL and HDCP columns) or 115 (for the name column) provides the necessary V-LINE output signals.
- a repetitive count of 7 comprised of 5 counts for each character (letter or number, both being printed in a 5-by-5 matrix) and 2 counts for the space preceding each character, provides the basic character space count. This basic count is multiplied by 3 for frames 1-9; by 4 for frame 10, and the TOTAL and HDCP columns; and by 16 for the name column.
- each dot element R1-R68 The major timing limitation with respect to the energization of each dot element R1-R68 is that when a dot has been fired, the signal must remain applied for five milliseconds in order to heat the thermal paper. This is accomplished by strobe lines S1-S4 which time the energization of each dot print resistor after selection by the data lines. One shot multi-vibrator 30 provides the five-millisecond timing pulse.
- the paper advance 6 is simply a strobe signal applied through an amplifier to the solenoid 6S of stepping motor 6M in timed relationship to the printing of each column of dots.
- the PRINT FAIL signal is developed as follows:
- the outputs 35-38 of the drivers 50-53 are applied to an A2J transistor inverter 54 via diode OR-gate 55. These outputs are normally low, i.e., they track the state of the input signals S1-S4 on lines 39-42.
- the output of the inverter 54 is therefore normally high, holding A2J inverter 56 low and preventing a print fail signal. If a transistor in any driver section 50-53 fails or shorts out, the output of that section will go high, forcing the output of inverter 54 low and allowing the output of inverter 56 to go high, resulting in a PRINT-FAIL signal.
- the 4-quadrant print cycle is conducted with the paper at rest to avoid "wavy" lines in the output.
- paper motion can be and is initiated while the last quadrant is being printed, in order to increase print speed. This is possible for the following reasons.
- the paper motion cycle can be broken down into three phases: (1) solenoid actuation; (2) acceleration; and, (3) decelerction.
- Phase 1 takes place before acceleration, and requires about 7 milliseconds; this time is required to transfer energy into the solenoid through the rather large inductance in the coil.
- acceleration begins, speed increases to a peak, and then deceleration takes over.
- the combined acceleration-deceleration phases require an additional 7 milliseconds.
- Quadrants are printed in the order 0,1,2,3; each quadrant requires 5 milliseconds to print. Therefore, 3 milliseconds into quadrant 2, the paper advance strobe can be issued. Then, paper motion will not actually being until quadrant 3 signals have produced a print in the paper and terminated.
- the software counts out a 7 millisecond period to allow completion of the acceleration-deceleration phases.
- the 7 milliseconds' wait will be used to prepare the next 14 characters, i.e., 1 character per row, for printing the next column of the score card.
- the data characters to be printed on the next printout column are fetched from RAM 10 when this print pause is running, and after conversion the print sequence proceeds with printing this next printout column.
- the complete 5-by-5 matrix which will establish a complete character for each row where printing should occur, then the paper again moves past 2 dot spaces; if the frame is completed, all of the resistors not used to print the 5-by-5 data matrices on horizontal line are energized by a signal on a separate line V-LINE; simultaneously, signals are sent to leads M1-M20 and H.LINE.
- the vertical line of the scoring grid is formed on the paper. Breaking down of the characters into rows of 5-by-5 word matrices and printing of both characters and grid lines in this dot-type fashion allows high-speed printing of all the game score data for all the players on a team participating in a game.
- the result is a fast, readable, and accurate printout of game score data at any desired time in the course of a game.
